2020 Course Time Cut Offs and Pre-Riding
Time Cutoffs - There are five areas on the course where there will be a time cutoff:
A - Loop 1 - Top of Telluride Trail - 9:00AM
B - Loop 1 - Bottom of Magic Meadows trail and Hwy 145 - 11:00AM
C - Starting Loop 2 - Start/Finish area at Gondola Plaza - 12:30PM

Time cutoffs are in place for rider safety. Sweep riders are sent out at the cutoff time and all course marshals and feed zones will be taken down once the final sweep has passed their position. Riders that do not make the time cutoffs will be scored as DNF (did not finish).
